<![CDATA[ABSTRACT The family has an important role in the health care of patients with type 2 diabetes mellitus (T2DM), including diabetes mellitus self-management (DMSM). To carry out the role properly, the family must have adequate knowledge. Previous research has found that the implementation of DMSM in T2DM sufferers and family support is low. This study aims to identify family knowledge related to DMSM. This quantitative descriptive study with a cross-sectional approach involved 188 families of T2DM patients who were taken through a purposive sampling technique. Data were collected through a respondent characteristic questionnaire, and a family knowledge questionnaire related to DMSM which had been translated through the back-forward translation method into Indonesian and modified with an inter-item correlation between 0.205-0.527, and Chronbach alpha 0.660. The collected data were analyzed descriptively. Half of the respondents had good knowledge (50%) with the lowest mean in the domain of pharmacological therapy (1.07±0.60), foot care (1.40±0.73), and physical exercise (1.69±0. 54). The low pharmacological therapy domain, physical exercise, and foot care need special attention. It is important for health workers to seek to increase family knowledge so that they can help patients carry out DMSM, especially aspects of pharmacological therapy, physical exercise, and foot care. Keywords: Family Support, Knowledge, Self Management, Type 2 Diabetes Mellitus ABSTRAK Keluarga memiliki peran penting dalam perawatan kesehatan pasien diabetes melitus tipe 2 (DMT2) termasuk dalam melakukan self-management diabetes melitus (SMDM). Untuk menjalankan perannya dengan baik, keluarga harus memiliki pengetahuan yang adekuat. Penelitian terdahulu menemukan pelaksanaan SMDM pada penderita DMT2 dan dukungan keluarga yang rendah. Penelitian ini bertujuan untuk mengidentifikasi pengetahuan keluarga terkait SMDM. Penelitian deskriptif kuantitatif dengan pendekatan cross-sectional ini melibatkan 188 keluarga pasien DMT2 yang diambil melalui teknik purposive sampling. Data dikumpulkan melalui kuesioner karakteristik responden, dan kuesioner pengetahuan keluarga terkait SMDM yang telah dialihbahasakan melalui back-forward translation method ke Bahasa Indonesia dan dimodifikasi dengan inter intem correlation antara 0,205-0,527, dan chronbach alpha 0,660. Data yang terkumpul dianalisis secara deskriptif. Setengah responden memiliki pengetahuan baik (50%) dengan mean terendah pada domain terapi farmakologi (1,07±0,60), perawatan kaki (1,40±0,73), dan latihan fisik (1,69±0,54). Rendahnya domain terapi farmakologi, latihan fisik, serta perawatan kaki perlu mendapatkan perhatian khusus. Penting bagi petugas kesehatan untuk mengupayakan peningkatan pengetahuan keluarga sehingga dapat membantu pasien menjalankan SMDM terutama aspek terapi farmakologi, latihan fisik, dan perawatan kaki.
